    Area of Science:

    • Immunology
    • Endocrinology
    • Nutritional Science

    Background:

    • Iodine has historical therapeutic uses in various immune-mediated diseases.
    • Its role in modulating immune responses, independent of antimicrobial action, is recognized.
    • Conditions like erythema nodosum and Sweet's syndrome have shown benefit from iodine therapy.

    Purpose of the Study:

    • To investigate the relationship between dietary iodine intake and immune response in infants.
    • To assess the impact of iodine supplementation on immune markers.
    • To establish a correlation between iodine levels and immune system function.

    Main Methods:

    • A study involving 607 infants in an endemic goiter region.
    • Two groups were formed: one receiving Lugol solution (iodine supplement), and a control group.

  • Immune response was evaluated using a tetanic toxoid skin test, lymphocyte stimulation, and monocytic chemotaxis tests.

    • Main Results:

    • A statistically significant difference (P < 0.001) was observed in the average skin test infiltration diameter between the iodine-supplemented and control groups.
    • The iodine-supplemented group demonstrated a markedly enhanced immune response.
    • The findings suggest a positive correlation between iodine intake and immune system performance.

    Conclusions:

    • Adequate iodine intake appears necessary for a normal and robust immune response in infants.
    • The study indicates iodine's essential role in supporting immune function.
    • Further research is needed to elucidate the specific molecular mechanisms underlying iodine's immunomodulatory effects.
